    • 12 can be negative. Equation 2 in the text defines work of adhesion completely in terms of interfacial energies because the pull-off experiment is carried out under solvent. Any of the interfacial energy terms in eq 2 can be positive or negative in principle.

    • 3 at 538 nm vs 530 nm for [TMPD-TCNQ]. Excitation energies of CT complexes have been shown to decrease with decreased ionization potential of the electron donor. However, I and II are less effective in forming a CT complex (ΔGcomplex = -12kJ/mol vs -14 kJ/mol for [TCNQ-TMPD]). This clearly shows that factors other than the redox properties of the participating molecules affect complex formation.

    • In previous AFM studies, the value most commonly used for K is the value for an Au-Au contact (64 GPa, see for example refs 8g and 8k). As the measured rupture force gets smaller, however, the size of the contact area approaches molecular scale dimensions and K approaches the value for the SAM, ∼1 GPa.
